这个时间轴是工作上用到的，自己写了一个， qq空间有时间轴的控件， 百度文库也有时间轴的控件；
百度的时间轴大概是这样的：
用户点击对应的锚链接， 那个三角会滚动， 然后左侧的界面也会滚动；
实际的效果如下图，用户点击左侧的按钮或者右侧的input，滚动条都会主动滚动， 这里有个小技巧就是用after和before伪类生成三角形， 用户点击按钮的滚动效果直接用jq的animate方法：
<!--//设置内容;window.onWebMessage( '{"type":"setItems","data":{"items":[{"name":1111},{"name":2222}]}}' ) ;//设置内容, 对应的item对象如果active为true为激活态;window.onWebMessage( '{"type":"setItems","data":{"items":[{"name":1000},{"name":1111},{"name":2222},{"name":3333,"active":true}]}}' ) ;//设置某个第n个位置的item;window.onWebMessage('{"type":"setItem","data":[2,{ "name" : "add-item"}]}');//激活第三个锚链接为选中态;window.onWebMessage( '{"type":"active","data":2}' )//获取目前的数据:window.onWebMessage( '{"type":"getItem"}' );--><html> <head> <meta charset="utf-8" /> <script src="http://cdn.bootcss.com/jquery/2.1.4/jquery.js"></script> </head> <style> /*初始的reset样式*/ *{ margin:0;

运行下面代码
<!DOCTYPE HTML><html><head> <meta charset="utf-8"/> <style type="text/css"> #div1 {width:488px;height:70px;padding:10px;border:1px solid #aaaaaa;} </style> <script type="text/javascript"> //当元素dragover时候一定要阻止默认事件， 否则把当前拖拽的元素就无法drop; function dragover(ev) { console.log(ev); ev.preventDefault(); } //对于拖拽事件最重要的一个事件属性就是dataTransfer; function drag(ev) { console.log(ev); ev.dataTransfer.setData("Text",ev.target.id); } function drop(ev) { console.log(ev); var data=ev.dataTransfer.getData("Text"); ev.target.appendChild(document.getElementById(data)); } </script></head><body><p>请把图片拖放到矩形中：</p><div id="div1" ondrop="drop(event)" ondragover="dragover(event)"></div><br /><img id="drag1" src="http://images0.cnblogs.com/news/24442/201507/081152502219706.gif" draggable="true" ondragstart="drag(event)" /></body></html> 另外一个DEMO：运行下面代码<!DOCTYPE HTML><html><head> <meta charset="utf-8"/> <style type="text/css"> </style></head><body> <p>What fruits do you like?</p> <ol ondragstart="dragStartHandler(event)"> <li draggable="true" data-value="fruit-apple">Apples</li> <li draggable="true" data-value="fruit-orange">Oranges</li> <li draggable="true" data-value="fruit-pear">Pears</li> </ol> <script> var internalDNDType = 'text/x-example'; // set this to something specific to your site function dragStartHandler(event) { if (event.target instanceof HTMLLIElement) { // use the element's data-value="" attribute as the value to be moving: event.dataTransfer.setData(internalDNDType, event.target.dataset.value); event.dataTransfer.effectAllowed = 'move'; // only allow moves } else { event.preventDefault(); // don't allow selection to be dragged } } </script> <p>Drop your favorite fruits below:</p> <ol ondrop="dropHandler(event)" ondragover="dragover(event)"> <!-- don't forget to change the "text/x-example" type to something specific to your site --> <li>drop</li> </ol> <script> var internalDNDType = 'text/x-example'; // set this to something specific to your site function dropHandler(event) { var li = document.createElement('li'); var data = event.dataTransfer.getData(internalDNDType); if (data == 'fruit-apple') { li.textContent = 'Apples'; } else if (data == 'fruit-orange') { li.textContent = 'Oranges'; } else if (data == 'fruit-pear') { li.textContent = 'Pears'; } else { li.textContent = 'Unknown Fruit'; } event.target.appendChild(li); }; function dragover(ev) { ev.preventDefault(); }; </script></body></html>HTML5的拖拽提供了 setDragImage ， effectAllowed ， setData.... 等很多便捷的方法给开发者, 通过FileReader读取File， 然后就可以用ajax与后台进行交互， 和前端DOM操作：
<!DOCTYPE HTML><html><head> <meta charset="utf-8"/> <style type="text/css"> </style></head><body> <div id="div0" ondragover="dragover(event)" ondrop="drop(event)"> drop拖放文件进来 </div> <script> function dragover(ev) { ev.preventDefault(); }; function drop(ev) { var reader = new FileReader(); reader.onload = function ( ev ) { var oDiv = document.createElement("div"); oDiv.innerHTML = ev.target.result; document.body.appendChild( oDiv ); }; reader.readAsText( ev.dataTransfer.files[0] ); ev.preventDefault(); } </script></body></html>插件效果图：
